Frequently Asked Questions
Everything you need to know about concrete work in Seattle, from costs to curing times.
Quick Navigation
What is concrete flatwork and what services does it include?
Concrete flatwork refers to any poured concrete surface that is essentially flat — including driveways, patios, sidewalks, garage floors, and foundation slabs. As Seattle's premier concrete flatwork contractors, we specialize in all horizontal concrete applications with proper drainage, reinforcement, and finishing for the Pacific Northwest climate.
How much does a concrete driveway cost in Seattle?
For professional installation in 2026, homeowners can typically expect to pay between $13 and $24 per square foot, depending on the thickness, reinforcement, and finishing choices. Site accessibility and the need for slope stabilization can also impact the final price.
How long does concrete take to cure in Seattle's climate?
Initial set occurs within 24 hours, meaning you can walk on it with light shoes. However, curing takes 28 days to reach full structural strength. We recommend waiting 7 days before driving standard vehicles on a new pour, and 14-21 days for heavy trucks or equipment.
Do you handle the permitting process with the City of Seattle?
Yes, for most structural projects and work within the public right-of-way (like sidewalks), we manage the entire permit application and inspection scheduling process with SDOT and DPD to ensure your project is fully compliant.
Is stamped concrete slippery when wet?
While any smooth surface can be slippery when wet, we add specialized slip-resistant shark-grip additives to our sealers to ensure that even highly decorative stamped surfaces remain safe and walkable during Seattle's frequent rainy months.
What is the best time of year to pour concrete in Washington?
While we can pour year-round using specific weather admixtures, the most ideal window is between mid-April and early October. During winter, we monitor humidity and temperature closely to ensure the hydration process is not interrupted by frost or excessive saturation.
Why does concrete crack, and can it be prevented?
Concrete naturally shrinks as it cures, which can cause minor hairline cracks. We prevent significant cracking by using precision-cut expansion joints, heavy-duty rebar reinforcement, and high-quality subgrade compaction. We also use fiber-reinforced mixes for extra tensile strength.
What warranty do you offer on concrete work?
We provide a 10-year structural warranty on all concrete flatwork including driveways, patios, and foundations. This covers structural integrity and major cracking due to workmanship. Minor hairline cracks from natural curing are normal and not covered, but we take extensive measures to minimize them.
How do I maintain my concrete driveway in Seattle?
We recommend resealing your concrete every 3-5 years to maintain moisture protection. Keep the surface clean by power washing annually, and avoid using deicing chemicals which can cause surface spalling. Address any cracks promptly to prevent water infiltration and further damage.
Can you pour concrete in the rain?
Light rain after the concrete has set is not a major issue, but we avoid pouring during active rainfall. Seattle's frequent drizzle requires careful scheduling. We monitor forecasts closely and use protective covers when needed to ensure proper curing and finishing.
What's the difference between concrete and cement?
Cement is actually an ingredient in concrete. Concrete is made by mixing cement (the binding agent) with water, sand, and aggregate (gravel or crushed stone). So when you have a 'cement driveway,' it's technically a concrete driveway.
Do you offer colored or stained concrete options?
Yes! We offer integral color (mixed throughout the concrete before pouring), acid staining for unique mottled effects, and water-based stains for a wider color palette. Integral color is most durable since the color runs through the entire slab depth.
How thick should a concrete driveway be?
Standard residential driveways should be at least 4 inches thick. For driveways that will support heavy vehicles like RVs or delivery trucks, we recommend 5-6 inches with heavier reinforcement. The subbase preparation is equally important for long-term durability.
What areas do you serve?
We serve all Seattle neighborhoods including Ballard, Queen Anne, Capitol Hill, West Seattle, Fremont, and more. We also cover greater Seattle areas including Bellevue, Kirkland, Redmond, Renton, Burien, Shoreline, and surrounding communities.
How long does a concrete project typically take?
Most residential projects take 1-3 days for the actual pour, depending on size and complexity. However, you should plan for 1-2 weeks total including preparation, curing time, and any finish work. Larger commercial projects may take longer.
